Battery Draw Bogus Math? Peukert UPDATE 2
Update- 11 Oct 20, Update 2- 12 Oct 20 Thinking one 100AH battery that can be drawn down to very low SOC gives you nearly the same "usable AH" as two regular AGM or Wet batts, as seen advertized, ...

Close enough for discussion.
So you gain 5% by having 2 AGM to reduce the load from the 10 hr to the 20 hr.
I believe when you compare that to a single lithium of similar capacity you will not lose that 5% for staying with the single battery and discharging at the 10 hr rate and just going deeper to yield the same energy. Internal resistance and peukert effect is very close to zero with lithium.
And a flooded cell battery will be worse than the AGM.
